Question

упаковку корма лайка съедает за 30 дней лабрадор за 24дня овчарка за 20 дней.ЗА сколько дней три собаки съедят упаковку корма вместе.

Answer 1

Ответ:

Пошаговое объяснение:

1/30 + 1/24 + 1/20 = 1/8 (узнаем какую часть корма собаки съедают за день). Соответственно весь корм съедят за 8 дней.

Answer 2

To find out how many days it would take three dogs (a Labrador, a Shepherd, and a Husky) to finish the dog food together, we need to calculate their combined rate of consumption.

Let's start by finding out how much food each dog eats per day:

• The Labrador eats the entire package in 30 days, so it eats 1/30 of the package each day.
• The Shepherd eats the entire package in 24 days, so it eats 1/24 of the package each day.
• The Husky eats the entire package in 20 days, so it eats 1/20 of the package each day.

Now, we'll calculate the combined rate of consumption for all three dogs: Combined rate = Labrador's rate + Shepherd's rate + Husky's rate Combined rate = 1/30 + 1/24 + 1/20

To add these fractions, we need to find a common denominator. The least common multiple (LCM) of 30, 24, and 20 is 120.

Combined rate = (4/120) + (5/120) + (6/120) Combined rate = (4 + 5 + 6) / 120 Combined rate = 15/120

Now, let's simplify the combined rate fraction: Combined rate = 1/8

This means that together, the three dogs eat 1/8 of the package each day.

Finally, to determine how many days it will take them to finish the package together, we need to find the reciprocal of the combined rate: Number of days = 1 / Combined rate Number of days = 1 / (1/8) Number of days = 8

So, it will take three dogs (Labrador, Shepherd, and Husky) 8 days to finish the entire package of dog food when they eat together.
